How the Oasis OH18 Protects Your Ukulele

Oasis OH-18 Ukulele Humidifier Installed in the SoundholeWhen mounted in your uke’s soundhole, the USA-made Oasis OH18 Ukulele Humidifier protects your instrument against hairline cracks that might result from drying out. What sets the OH18 apart from many other soundhole-mounted humidifiers is its elegant anti-leakage design. Soundhole humidifiers that use foam or sponge to hold water may provide adequate defense against dry environments, but fail to protect the instruments from potential leakage from the humidifiers themselves. The Oasis OH18 prevents water leaking into your uke in two ways:

  1. The OH18 reservoir is made from a specially designed fabric that allows vapor to pass through it and humidify your ukulele while blocking the passage of water.
  2. The super absorbent Humigel crystals inside the OH18 turn water into jelly. This enables the water to evaporate and humidify your uke, but prevents water leaks should the humidifier become damaged.

To further protect your instrument, the Oasis OH18 is made from soft materials so it will NOT damage your strings or dent or scratch your uke.

As water vapor is dispensed from the OH18, the humidifier shrinks, making it easy to tell when it needs a refill. The included 10cc syringe makes filling the humidifier a snap. Because the minerals contained in tap or bottled water may clog the liner, distilled water is recommended to extend the life of the humidifier.

When Should You Use the Oasis OH18?

The Oasis OH18 humidifier is suitable for moderately dry environments with humidity levels between 25% and 40%. In conditions above 40% humidity, you should NOT use a humidifier. Typically, humidity drops in the fall and rises in the spring, so you may not need to humidify your uke all year round. It’s best to use hygrometers to determine the exact humidity levels both inside and outside your ukulele case or bag.
